The theoretical composition of the C6-C11 bioalcohol fraction in the ultimate Redifuel biofuel has been estimated based on the intrinsic reaction kinetics afforded by the 1st generation FT and hydroformylation catalysts. This composition has been shared with partners to prepare surrogate alcohol mixtures, from commercial pure alcohols and blends thereof. This synthetic mixture enables work around the fuel matrix design and preliminary engine tests to set in before relevant amounts of the biofuel are produced later in the project.
- Objective: To avail of a surrogate C6-C11 alcohol mixture as a suitable replacement for the corresponding bioefuel belnd fraction to initiate fuel matrix and combustion studies earlier in the project.
- Research: The composition of the mixture was determined from experimental tests of the 1st generation FT and hydroformylation catalysts employed by the consortium (developed by the CSIC and MPI partners, respectively).
- Result: The composition for a C6-C11 acohol mixture including both n-alcohols and 2-methylalcohols.
- What will it be used for: To initiate fuel matrix design and preliminary engine studies before relevant amounts of the biofuel are produced later in the project.
- Impact: The development of this surrogate mixture enables progress in areas of the project concerning fuel combustion to set in before relevant amounts of the real biofuel blend is obtained in the context of piloting activities.
